Old DVD player – what should I salvage?

We own two DVD players.  Well, three.  Well, four – but one is a portable DVD player for trips and one is a replacement for one of the first two.   The first two are really old – and were just failing.  They had problems loading DVD’s or just even turning on.  I was curious what I would find inside.

Of interest I found a bunch of small motors, a few LED’s, springs, magnets, tiny mirrors, rubber belts and super tiny precision rods.

There are obviously lots of little capacitors and whatnot.  What else should I pull out of these things?
